Definitions
- This invention relates to thermal camera arrangements and more particularly to arrangements which enable an operator to use a thermal camera whilst being free to use his hands.
- Thermal cameras produce visible images representative of the thermal intensity of viewed scenes. They are particularly useful in fire fighting and search and rescue applications as they enable an operator to see through darkness or dense smoke.
- a thermal camera arrangement comprises a helmet having a faceplate and a thermal camera mounted on the helmet arranged such that a wearer of the helmet can view the output of the camera, the optical path through free space from the camera output to the wearer's eye being substantially wholly within a volume defined by the helmet and the faceplate.
- the faceplate is integral with the helmet, the faceplate being permanently fixed to the helmet and being surrounded by it. It is also preferred that the helmet and faceplate substantially wholly enclose the wearer's head. This gives maximum protection to the wearer and effectively isolates the volume defined by the helmet and the faceplate from the environment, and hence from any smoke or other substance which may attenuate the output from the camera.
- the arrangement enables both eyes of the wearer to view the output of the camera.
- the output of the camera is reflected from a surface within the volume before impinging on the wearer's eye.
- the surface may be a silvered portion of the faceplate or may be a separately provided mirror.
- the mirrored surface may be fully or half silvered, the latter enabling the wearer to view the output of the camera superimposed on the external scene.
- the surface is located below the sightline of the wearer when he is looking ahead. Thus, by looking ahead normally he sees the scene unaided by the thermal camera and by looking down he sees the output of the camera.
- a lens is included in the optical path between the camera output and the wearer's eye, to enable the image to be more easily focussed.
- the lens may be located adjacent to the camera output but preferably it is combined with the mirrored surface, which may be deposited on a surface of the lens. It is preferred that the lens is of a plastic material, such as for example a polycarbonate material which, compared to a glass component, reduces the risk of injury to the wearer should it be damaged.
- a mirror/lens combination it is concave, enabling the image to be easily focussed, even if the mirror is only a short distance in front of the wearer.
- the helmet is one which includes breathing apparatus, especially of the type which requires a seal around the face. If a mirror or mirror/lens combination is included, it may be mounted at an intake of the breathing apparatus, where this is included, as forward vision is restricted in this region in any case. Where a mask covering the wearer's nose and mouth is employed, the mirror or mirror/lens combination may be conveniently mounted on the mask, conforming to its outer surface.
- a window may be provided in a seal to allow the viewing output of the camera to be transmitted along a desired path. It may be advantageous to use a lens as the window.
- the camera is removably fixed to the helmet, enabling it to be removed if maintenance is required or to be fitted to different helmets in turn.
- the camera body is substantially wholly located within the helmet, preferably being located within a compartment separate from the wearer's head. If a protective harness is included to prevent the head from coming into contact with the helmet wall, the camera is preferably positioned between the harness and the helmet wall. Although it is preferred that the camera is only removable from within the helmet when it is not being worn, it may be mounted so as to be externally accessible.
- the camera is positioned such that its faceplate is located above the eyeline of the wearer of the helmet.
- the camera is such that the direction of its viewing output is at an acute angle to its boresight direction.
- Such a "folded" configuration is compact and particularly suitable for the inventive arrangement.
- FIG. 1 is a schematic sectional view of a thermal camera arrangement in accordance with the invention.
- FIG. 2 is a schematic front view of the arrangement shown in FIG. 1.
- a thermal camera arrangement includes a thermal camera 1 mounted on a helmet 2 which completely encloses the head of a wearer 3.
- the helmet 2 includes an integral faceplate 4 which is large enough to afford the operator 3 extensive forward and sideways vision.
- a protective harness 5 attached to the inside of the helmet 2 cushions the wearer's head from blows to the helmet 2.
- the helmet 2 also incorporates breathing apparatus having an exhaust diaphragm 6, mask 7 which covers the nose and mouth and pipes 8 leading an air supply.
- a seal 9 surrounds the face of the operator.
- the thermal camera 1 is removably mounted within the helmet 2, being located in part of the space between the helmet wall and the protective harness 5.
- the camera faceplate 10 on which incident thermal radiation impinges is located above the eyeline of the wearer, as can be seen in FIG. 2.
- the camera 1 is of a "folded" configuration such that its boresight direction and the direction of its viewing output are at an acute angle to each other.
- the output of the camera 1 is passed via a sealing window 11, which in this embodiment is also a lens, in the face seal 9 and impinges on a concave mirror/lens combination 12, the light being transmitted through the lens 12A and being reflected by its silvered rear surface 12B.
- the mirror/lens combination 12 is attached to the mask 7 and has a surface which conforms to the outer surface of the mask 7.
- the mirror/lens combination 12 is located below the forward sightline of the wearer 3. Thus, as shown in FIG. 1, by looking straight ahead, the operator sees the scene without the aid of the camera 1 and by looking down he sees the camera output.
- the mirror/lens combination 12 is so positioned that both eyes can see the image from the camera 1 without difficulty.
- a cap lamp 13 may also be included, as shown in FIG. 2, being located above the right eye of the wearer and arranged to illuminate the viewed scene.
- the lamp 13 is useful for conditions in which smoke or other obscuring gases are not present.
- a cap lamp which is interchangeable with the thermal camera may be available, so that the appropriate equipment may be chosen depending on conditions.
